CATALYST INK FOR FUEL CELL ELECTRODES, MEMBRANE ELECTRODE ASSEMBLY, FUEL CELL

摘要

This catalyst ink, which is used for manufacturing fuel cell electrodes, includes catalyst carrier particles, which are particles that carry a catalyst, ionomers that have proton conductivity, and a dispersion solvent that disperses the catalyst carrier particles and the ionomers. The amount of the ionomers that are adsorbed per unit specific surface area of the catalyst carrier particles is at least 0.1 (mg/m2).
